Targeted at power supply, ballast and general-purpose industrial electronics, the UCS2G680MHD delivers high ripple-current capability and extended endurance for designs operating across a wide temperature range.

Key Features

• Electrical Performance — 68 µF capacitance with a tolerance of −20% to +20% and a rated voltage of 400 V for high-voltage DC applications.
• High Ripple Current — Low-frequency ripple current 735 mA at 120 Hz and high-frequency ripple current 1.47 A at 100 kHz, supporting demanding power conditioning tasks.
• Loss Characteristics — Tan δ (DF) of 0.24 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics in designs.
• Long Endurance — Rated life of 10,000 hours at 105°C, providing extended operational reliability under elevated temperature stress.
• Wide Operating Temperature — Operates from −40°C to +105°C to accommodate industrial temperature environments.
• Leakage Current — Specified leakage current of 1,188 µA (measured after 1 minute at 20°C with rated voltage), useful for power budget and standby calculations.
• Compact Radial Package — Can dimensions φ18 × 25 mm (L) with 7.5 mm lead spacing (±0.5 mm) in a radial-lead can package for through-hole mounting and easy PCB placement.
• Packaging & Production Status — Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Power Supplies — Bulk and smoothing capacitor for high-voltage DC rails where 400 V rating and high ripple capability reduce voltage ripple and improve regulation.
• Ballasts and Lighting Electronics — Suited for ballast applications requiring high ripple endurance and long life at elevated temperatures.
• Industrial Control Equipment — Filter and decoupling capacitor in motor drives, inverters and other industrial power electronics that operate across −40°C to +105°C.
• General-Purpose High-Voltage Circuits — Through-hole radial mounting simplifies replacement and prototyping in a variety of high-voltage designs.

Unique Advantages

• High Ripple Handling: Rated ripple currents of 735 mA (120 Hz) and 1.47 A (100 kHz) let designs tolerate heavy AC ripple without premature degradation.
• Extended Life at Elevated Temperature: 10,000-hour rating at 105°C supports longer maintenance intervals and stable long-term performance in hot environments.
• High Voltage Capability: 400 V rating enables use on higher-voltage DC rails and in applications that need substantial voltage margin.
• Compact Radial Form Factor: φ18 × 25 mm can size and 7.5 mm lead spacing provide a space-efficient solution for through-hole layouts.
• Predictable Dissipation and Leakage: Specified tan δ and leakage current values aid thermal design and power-loss budgeting.
• Production Ready and RoHS Compliant: Mass production status and RoHS compliance simplify sourcing and regulatory alignment.
